Fig. 4.

Sample vocalization-related neural activity during trillphee calls. Examples are shown for units that were suppressed (A–C) and excited (D–F) during trillphees. A: simultaneously recorded vocal spectrogram (top) and extracellular neural recording trace (bottom) for a unit that exhibited vocalization-related suppression during trillphee vocalizations. B: raster plot for another example unit that was suppressed during a large number of vocalizations. C: PSTH of the trillphee vocalization responses illustrated in B. D: neural recording trace of a unit that exhibited vocalization-related excitation during trillphees. E and F: rasters (E) and a PSTH (F) for another example unit that was strongly excited by trillphee vocalizations.
